Jan. 10, 1967 C. J. VELARDOCCHIA TRANSISTOR RETAINER Filed July 1, 1965 INVENTOR COSMO J.VELARDOCCHIA ATTORNEY United States Patent 0 3,297,976 TRANSISTOR RETAINER Cosmo J. Velardocchia, Stoneham, Mass., assignor to Hewlett-Packard Company, Palo Alto, Calif., a corporation of California Filed July 1, 1965, Ser. No. 469,370 1 Claim. (Cl. 339-75) This invention is a device to retain transistors in their sockets.

FIGURE 1 is an exploded view and FIGURE 2 is an assembled view of the invention.

Referring to the drawing, a transistor comprises a can 3 having a rim 5 and a plurality of prongs 7. This transistor fits into a socket 9 having a rim 11 and a plurality of prong-receiving holes 13. Spring retainer 15 comprises two substantially parallel open loops 17 and 19 mechanically connected by a spring portion 21 which is substantially perpendicular to loops 17 and 19. Loops 17 and 19 wrap around the rims 5 and 11, thus securely retaining the transistor in the socket.

I claim:

In combination, a transistor having a flanged rim, a transistor socket having a flanged rim, a short member disposed adjacent said transistor and said transistor socket, said member being parallel to the axis of said transistor, first engaging means laterally extending from one end of said member and fitting substantially around the flanged rim of said transistor, second engaging means laterally extending from the other end of said member and fitting substantially around approximately half of the flanged rim of said socket, said first and second engaging means cooperating to clamp said transistor to said socket.
